Research on Variation of Sugarcane Red Rot ( Colletotri-chum falcatum Went) and Sugarcane Disease Resistance.

Sugarcane red rol caused by Colletotrichum falaitum Went is one of llie important fungal diseases causing significant losses to sugarcane production, commonly known as "cancer" of sugircane. It lias risen from a minor disease to a major disease, resulting in the death of sugarcane in Lineang, Menglian and Shi-ping sugarcane areas in Yunnan Province. Due to the frequent variation of lliis pathogen, it is difficult to control, the pesticide control effect is not ideal at present, and there is slill no elleclive and radical cure measures. The research on the variation of C. falaitum and sugarcane disease resistance is the only way to achieve the sustainable control of sugarcane disease. This paper mainly reviewed the genetic variation on the morphological, pathogenic and molecular variation of C. falcatum, and rapid molecular detection methods, and sugarcane disease resistance research in combination with the latest research al home and abroad. An outlook for further research on sugarcane red rol in the future was also given, to provide a theoretical basis for the research and control of sugarcane red rot in China. [ABSTRACT FROM AUTHOR]
